A method and device is provided for increasing the efficiency of jet drives by recuperating effective power from the propulsion flow. A ducted propeller in the propeller housing, driven by a driving engine via a drive shaft, conveys the fluid for the jet drive out of the interior Vi of a radial turbine. The fluid is accelerated axially and ejected backwards against the direction of travel. This creates thrust. Because the pressure in the interior of the turbine decreases, new fluid from the environment flows directly via the blades of the rotating radial turbine from the outside to the inside, thereby driving them. A guide apparatus is missing. The power of the radial turbine is transmitted via a transmission to the drive shaft of the propeller, which relieves the driving engine and increases the efficiency of the jet drive. The invention is particularly suitable for electric drives.
A method for increasing an efficiency of jet drives by recuperating effective power from a propulsion flow, characterized in that in a propeller housing a ducted propeller, driven by a driving engine via a drive shaft, conveys a fluid for the jet drive from an interior of a radial turbine, in that the propeller accelerates the fluid axially and ejects the fluid backwards against a direction of travel, in that a new fluid from an environment flows from an outside to an inside directly via blades of the radial turbine without a guide apparatus and thereby drives the radial turbine, and in that a power of the radial turbine is transmitted via a transmission to the drive shaft of the propeller, which relieves the driving engine.
A device for increasing an efficiency of jet drives by recuperating effective power from a propulsion flow, characterized in that in a propeller housing contains a ducted propeller, which is driven by a driving engine via a drive shaft, and in that the propeller housing contains a radial turbine without a guide apparatus through which fluid from an environment flows, wherein the fluid firstly flows through the radial turbine and then through the propeller, and in that the radial turbine is connected to a transmission by which power of the radial turbine can be transmitted to the drive shaft.
